Nu-Clo Hit Hard will shock you pool water with a boost of chlorine helping to remove algae and harmful bacteria as well as help you maintain crystal clear water year round.

The fast-acting 4-in-1 shock product kills bacteria and algae, restores crystal clarity to pool water within 24 hours, reduces chlorine odor and eye irritation caused by swimming pool water, and won't fade liners. It is convenient, easy to use and won't over stabilize your pool. One bag treats 13,500 gallons.

TO USE: Make sure your pH level is between 7.2 and 7.8 and adjust if needed.

Check that your pump is running and then snip the corner of the shock product. Broadcast over a wide area in the deepest part of your pool. If the granules settle at the bottom, use a brush to disperse them.

When your free available chlorine levels are between 1 and 4 ppm, your pool is ready for action.

68% Calcium hypochlorite; 68% Available chlorine.
